This project is to develop improved procedures for earthquake analysis and design of building with asymmetric plan. This type of buildings are least understood and generally suffered greater damage than symmetric buildings during past earthquakes. The research will be condicted to (1) study the earthquake response in the inelastic range, (2) develop simplified procedures for design, (3) evaluate the adequacy of torsional provisions in current codes, and (4) determine the optimal center for the reference center for flow eccentricity measurement and to the location of the code-specified equivalent lateral forces. The developments and results expected from this project will enable better evaluation of the response of asymmetric-plan buildings to earthquake ground motion, thus improving the capability to assess to the safety of existing buildings and of design proposed for structures to be consulted.

这个项目是为了开发改进的地震程序 平面不对称建筑的分析与设计。 这 建筑类型最不了解和普遍遭受 比过去对称建筑的破坏更大 地震 这项研究将致力于（1）研究地震 在非弹性范围内的响应，（2）开发简化的 设计程序，（3）评估扭转的充分性 现行法规的规定，（4）确定最佳的 流量偏心率参考中心的中心 测量和代码指定的位置 等效横向力 该项目的发展和预期成果将 能够更好地评估不对称计划的响应 建筑物的地震地面运动，从而提高了 评估现有建筑物安全的能力， 建议的结构设计进行咨询。
